BMW 745E PT can2 wake up message from EME to SME

[Flasher]

I bought a HV battery from a 2022 BMW 745e to use the 34 Ah cell packs for my BMW i8 which still has the old 20Ah cell packs.
This requires some adaptations because the two cell packs have different wiring and numbers of NTC's.
I also have the SME and CSC units from this HV battery for research but i can't communicate with this set because the SME is woken up by a CAN message from the EME (master) unit on the PT CAN2 bus instead of a +12v signal on the +15wup line.
Now i'm looking to find the wake-up message from the EME after key-on (+15 signal) but i can't find any info on this subject - a log file from the PT CAN2 bus during key-on would be perfect to find this wake up message but i don't have the belonging car and my i8 is woken up by a 12v signal on the +15 wup line.
Does any of you happen to have a log file from a 2022 hybrid BMW to share this info with me for investigation purposes ?
Of course i will post my findings if i find the wake up message....
thank you for any help !
